Engine fires up then idles low then returns to normal idle, and then when put in drive does same thing. I know the code has something to do with thermostat, low coolant, or coolant temp sensor, but does it relate to this? When I start the car cold, it fires up and then idles really low for about a second and then pops back up to regular idle. Then when I put it in drive and have my foot on the brake, the car does the same thing, but sometimes does it more than once. After this happens and it returns to normal idle, it drives fine. What would be the cause of this? Would this be related to the p0125 code? Any help is appreciated.
